We measure the branching fractions B(B0→K*0γ)=(4.47±0.10±0.16)×1− 5 and B (B+→K*+γ)=(4.22±0.14±0.16)×10−5. We constrain the direct CP asymmetry to be −0.033<A(B→K∗γ)<0.028 and the isospin asymmetry to be 0.017<Δ0−<0.116, where the limits are determined by the 90% confidence interval and include both the statistical and systematic uncertainties.7 p.application/pdfeng(c) American Physical Society, 2009Partícules (Física nuclear)Simetria (Física)Particles (Nuclear physics)Symmetry (Physics)info:eu-repo/semantics/article6019282018-10-03info:eu-repo/semantics/openAccess
